Abstract

Background and Aim: Eccentric muscle action has more mechanically efficiency, predisposes the muscle to damage due to unique activation strategy. Postural control also is necessarily required for many daily and sport activities. The purpose of this study was to investigate the effect of high velocity acute eccentric exercise-induced muscle damage of dominant knee extensors on MUSCLE DAMAGE INDICES and postural control in trained young females.Materials and Methods: Ten young trained females (21.9±1.66 years) voluntarily participated in this study. To analyse muscle damage, subjects performed 300 (20 sets, 15 repetitions) high velocity (240o.s-1) eccentric contractions of dominant knee extensors with a load equal to 150% of the maximal voluntary isometric torque (MVC).Muscle damage indices (MVC, perceived pain, thigh circumference) and center of pressure distance and velocity in the antero/posterior (AP) and the medio/lateral (ML) planes of movement were recorded before, 1 and 48 h after eccentric exercise. Statistical analysis was performed with SPSS (version 16.0), and the repeated-measures ANOVA test also were used.Results: All muscle damage indicators changed significantly (p<0.05) following eccentric exercise thats confirmed muscle damage. In contrast, no significant differences was observed for center of pressure distance and velocity in the AP and ML directions between all measured time points (p>0.05).Conclusion: In conclusion, the results of the present study showed that high velocity eccentric exercise that designed to elicit localized muscle damage of dominant knee extensors did not influence postural control during one-legged stance in trained young female.
